[Asterisk-java-users] Help about agi server

[dovb <do...@te...>]

Hi,
 
I have the following simple code:
 
After printing "cc1" (after I dial 123) the AGIServer prints
 
13/07/2005 23:28:05 net.sf.asterisk.util.impl.JavaLoggingLog error
SEVERE: AGIException while handling request: Unable to read reply from
Asterisk: Connectio
n reset
 
and stops running.
 
Where am I going wrong???
 
Thank you!
Dov

Hi Dov,

what version of Asterisk do you use?
can you post the relevant section of your asterisk console (use set
verbose 9 to enable full output)?

When I run your AGI script and press '123#' the channel is hung up at
SayDigitsCommand sc =3D new SayDigitsCommand(result);
because:
    -- Playing 'digits/1' (language 'en')
    -- Playing 'digits/2' (language 'en')
    -- Playing 'digits/3' (language 'en')
Jul 14 20:47:43 WARNING[801]: file.c:475 ast_openstream: File digits/#
does not exist in any format
Jul 14 20:47:43 WARNING[801]: file.c:779 ast_streamfile: Unable to open
digits/# (format alaw): No such file or directory

so I had to change that to
new SayDigitsCommand(result.substring(0, result.length() - 1));

after that everything went fine.
